| Ergonomics The applied science of equipment design intended to maximize productivity by reducing operator fatigue and discomfort.
The word, ergonomics, is derived from the greek words ergos meaning "work" and nomos meaning "laws"; therefore, we have the laws of work. The applied science of equipment design, as for the workplace, intended to maximize productivity by reducing operator fatigue and discomfort. Information
According to studies the ideal typing posture uses a
negative slope
keyboard support
In the ideal typing posture both static and dynamic muscle loads are minimized. This posture is achieved when the keyboard is below seated elbow height and the keyboard base is gently sloped away from the user so that the key tops are accessible to the hands in a neutral posture. In this position the arms, shoulders, neck and back can relax, especially during brief rest pauses. Also, in this slightly reclined sitting position the low back rests against the lumbar support of the chair, the elbow angle is opened to promote circulation to the lower arm and hand, the abdominal angle, and the popliteal angle (behind the knees) are opened to promote blood circulation. The feet rest firmly upon the floor. Links

Keyboarding: defined as the correct finger placement on the keyboard and entering words at about the same speed that the child can write using paper and pencil. When students become proficient in keyboarding, they will be able to enter words faster than they can be produced by using paper and pencil.
Word Processing:The use of a computer system to manipulate text. Note: Examples of word processing functions include entering, editing, rearranging, sorting, storing, retrieving, displaying, and printing text. Keyboarding should ALWAYS precede word processing. Learning to keyboard is not easy. It will take lots of self discipline and patience. Sometimes it takes weeks to show just small improvements. If you look at keyboarding as a skill that can be mastered with lots of practice you will do fine. One key factor to mastering keyboarding is good technique. Correct technique is the most important skill any beginning typist can learn. Speed and accuracy are all built around good technique. 1. Memorize the letters by not looking at your
hands while typing. Keystroking:Correct key stroking. You must use the correct finger to stroke each letter you are typing. Keep fingers curved. Don't look at your hands to type.
Home Row Position.
You should
always return your fingers back to home row after you have reached for
a key.  History of Typing The reason all the keys are mixed up was to speed up typing while slowing down the typist. True, history shows that Christopher Latham Shole in 1864 invented the machine called the "Type-Writer." Strangely enough, the first typewriter finally was designed to slow down the typist. Sholes had developed his machine for convenience, but was faced with a huge problem: the keys jammed if the typist went too fast. Sholes tried for months to fix this problem. Finally, in desperation, Sholes took a step that still remains today with our keyboard. Sholes redesigned the layout of the letters on the keyboard to force the typist to slow down. We call his layout the "QWERTY" keyboard (after the first six letters of the typewriter's second row). The first keyboard was first invented in 1864. The official name of the keyboard is "Qwerty". The keyboard is named after the top row of letters on the keyboard. If you don't think so just look on your keyboard. |
